Editor javadoc does not display parameter names

### Apache NetBeans version

Apache NetBeans 18

### What happened

When I hold down Ctrl and hover the mouse cursor over a constructor or method, the javadoc that popups does not display the names of the variables properly.

### How to reproduce

In a Java file, define a new BufferedImage(), hold down Ctrl, and hover the mouse cursor over the constructor name. It shows three parameters called i, i1, and i2, instead of width, height, and imageType.

### Did this work correctly in an earlier version?

Apache NetBeans 16

### Operating System

Windows 10 version 10.0 running on AMD64

### JDK

1.8.0_241

### Apache NetBeans packaging

Apache NetBeans provided installer

### Anything else

_No response_

### Are you willing to submit a pull request?

No

Start by reproducing the editor Javadoc popup in a Java file with a BufferedImage constructor, comparing the parameter display in NetBeans 18 and 16. Done means the popup shows width, height, and imageType instead of i, i1, and i2.
